IMPROVEMENT lN WASHING-MACHINES.

Specification forming part of Letters Patent No. 190,279, dated November23, 1875; application filed October 13, 1875.

To all whom it may concern Be it known that 1, JOHN DENIS LAWLOR, of thecity of Montreal, in the county of Hochelaga, Province of Quebec,Dominion of Canada, manufacturer, have invented a new and usefulImprovement on the VVashing-Machine secured to me by Letters Patent inthe United Stateson the 13th day of July, 1875,.and registered under thenumber 165,421, which improvement is fully set forth in the followingspecification, reference being bad to the accompanying drawing.

The object of my improvement is to provide a simpler and better means ofregulating the roller B of my washing-machine, so as to enable me to doaway with the various contrivances connected with the standard D of myoriginal invention.

In the accompanying drawing, Figure 1 represents a perspective view ofmy original invention, one side being cut away to show the internalarrangement of the different parts. Fig. 2 represents simply one of thestandards D, on which my improvement is located.

By comparing the standard D on Fig. 1 with that shown in Fig. 2 it willbe seen that I have done away with the pins 6, and spring m and block b,and substituted a much better and simpler mode of regulating the roller.

The spring-rod m instead of being fixed in a block, b, is set securelyin the block in which the shaft S is journaled, and its upper portion isprovided with a thread, on which a thumb-screw is placed. When thisthumbscrew, as represented at K, is turned to the right, the spring-rodm is raised, causing the block in which the shaft S of the roller B isjournaled to rise, thereby raising the roller, which it becomesnecessary to do when it is desired to adjust the machine for doing heavywashing-such as sheets, blankets, 850. When these require any extraamount of pressure it does not become necessary to lower the roller,

as its own weight adds considerably to that of the tension of thespring.

When it is desired to wash small light pieces the thumb-screw K isreversed, and the block in which the shaft S is journaled is lowered,carrying, of course, the roller with it.

Having thus described the nature of my improvement, what I claim as new,and desire to secure by Letters Patent, is

In a washing-machine, constructed as hereiubefore described, thespring-rod m constructed with a screw-thread on its upper end, providedwith the thumb-screw K, and connected at its lower end to the block inwhich the shaft S of the washing-roller is journaled, substantially asand for the purpose set forth and described.

In testimony that I claim the foregoing as my own invention I affix mysignature in presence of two witnesses.

JOHN DENIS LAWLOR.
